JOHN F. KELLER, 0F GREENCASTLE, PENNSYLVANIA.'

.Speciieationforming partA of Letters Patent No. 31,084, dated January 8, 1861.

To all whom it may concern.

ABe it known thatl, JOHN' F. KELLER, of ncastle, in the county of VFranklin and State of Pennsylvania, have invented certain new and useful Improvements in Guano Attachments to Wheat-Drills; and-1 do hereby declare that the'v following is a full and exact- `description thereof, reference being had to the accompanying drawings, and to theletters'of reference-marked thereon.- n

In constructing machines for sowing guano it is found difficult to prevent the bridging and 'clogging of the machine. The greasy adhesive naturoof the guano requires a certain amount of jar'in the stirrer torender the feeding reguiar 'and complete.- '.llher'e'm`l-1si', also be some arrangement of breakers to crush. the hard lumps'orbones-occurring in most guano.-

My invention consists in a peculiar and improved arrangement of stirrers, gearing,"and clearers for guano attachment to wheat-drills,

In the accompanying drawings,-Figure 1 is a top view of my improved guano attachment.

Fig. 2 is an elevation of the same. 'l3igs.'3

I n the drawings, Arepresents the box or' v'bumperintl). which the guano is put for sowing. In this hopper is a' sere'smf'spike-rollers, B, for stirring the guano and breakingthe .lumps orboneso'f thesame previous toits he# ing scattered upon theground. These rollers .are 'turned forward and backward through a partial' revolution by the cranks v 0,' 'which ref cev'e reciprocating motion fromthe bar D'and .connecting-rod E, so `'that the guanolis com stantly'agitated infthehopper, lThe guano passes through between these rollers in order and 'they sweep across the.disehargeopenin gs at every stroke of the rollers, thel beveled spikes forcing the guano down through the ldischargefopeni'ngs, and thus keeping themselves free from adhesions of guano.

7 represent detached parts of the ma'-l chine'. w

the bottom of the hopper, and contains the discharge opening G. These openings 'are .made in a peculiar manner. The lower side ofthe slide is cut away so as to leave a sharp edge on the upper side, as seen in Fig. 6, for. the purpose of preventing the holes from clog'- Vging. In order to insure the'regular feed, and to guard'against the possibility of clogging,

I have arranged under the hopper a series of clearers, H, which play up and down in holes G. These clearers are operated by means of a rock-shaft, I, which receives motion from lever L, connecting-rod M, and crank N, as seen in Fig.2. The length of this clearer H is seen inFig.7.. v

Motion is given to the machine by means of the traveling wheels in 'the usual manner. This shaft O carries a cog-wheel, S, which op-v ;erates the pinion T andcrank-shaft U, and also a crank,l V, which gives motion to the yconnecting-rod. W. The elbow X is con'- nected'withithe rod W by means of a freeworkiu'g collar provided with pivots at each side, so as to produce a universal joint of pej culiar construction.. By these means motion' is communicated to the rod E,l.bar D,"an'd.

bow X; or the sowing of the guano may be stopped by placing thehand upon lever P,

Patent of the United States, is' l l. The arrangement of a seriesr'if` spiked rollers B, when placed vertically and moved.

The slide R,' Figs. 5 and 6, forms a part of the shaft O, w.hieh may-be set in motion' by rollers B. The rod E is made detachable from elbow X in Order to' stop the actionof the rollers at pleasure. Thuswhenever thedrver' wishes tostop the motionof the rollers he 1 has only to lift the end of rod'E .from the el# fully described my invention,
